If you’re looking for a premium lubricity additive with revolutionary science behind it, Hot Shot’s Secret LX4 Lubricity Extreme can make your fuel up to two times slicker. We designed LX4 Lubricity Extreme to help the poorest-quality diesel increase lubricity up to 56%.

Hot Shot’s Secret LX4 Lubricity Extreme works best with low-lubricity, ultra-low sulfur diesel (ULSD), and gasoline. Our formula is essential for farm equipment, semi-trucks, pickups include GM Duramax, Ford Powerstroke, and Ram Cummins engines along with other vehicles. Every bottle of our LX4 Lubricity Extreme is free from solvents and alcohol and is safe for all emissions systems.

All vehicles that use diesel “dry fuel,” like Class 8 and pickup trucks, are compatible with our entire line of Hot Shot’s Secret fuel additives, such as:

  • Diesel Extreme.
